The magnicellular system seems to be affected early and specifically by glaucomatous damage. It shows high temporal resolution and good motion perception. Psychophysical tests investigating the temporal transfer characteristics of the afferent visual system thus are of special interest for the detection of early glaucomatous damage. Flicker perimetry is largely independent from disturbances of the ocular media and provides a means to identify eyes with pressure-produced functional loss. Defects in temporal modulation perimetry may precede the onset or progression of defects in conventional light-sense perimetry. Motion sensitivity seems to be affected early by glaucomatous damage. The problem of noisefield campimetry is the lack of quantification and reliability control of the patients' responses. Large-field or Ganzfeld stimulators can separate glaucomatous from normal eyes with high sensitivity and specificity; their value for the identification of eyes at risk to develop progression of functional loss still must be demonstrated.
大细胞系统似乎早期就会受到青光眼性损害的特异性影响。它具有高时间分辨率和良好的运动感知能力。因此，研究传入视觉系统时间传递特性的心理物理学测试对于早期青光眼性损害的检测具有特殊意义。闪烁视野检查在很大程度上不受眼内介质干扰的影响，并提供了一种识别因眼压导致功能丧失的眼睛的方法。时间调制视野检查中的缺陷可能先于传统光感视野检查中缺陷的出现或进展。运动敏感性似乎早期就会受到青光眼性损害的影响。噪声场视野检查的问题在于患者反应缺乏量化和可靠性控制。大视野或全视野刺激器能够以高敏感性和特异性区分青光眼患者和正常眼睛；但其在识别有发生功能丧失进展风险的眼睛方面的价值仍有待证明。
